Beauty Police: Is Getting Your Roots Touched Up So Last Season?

We noticed an interesting trend this Mercedes-Benz New York Fashion Week,–and it had nothing to do with the clothes. We know the lived-in look is becoming cool, but a bevy of celebs–from socialites to models– were rocking what is generally considered a beauty faux pas: lots of roots.

The newest trends can always been found on three types of people: stylists, models, and socialites.  From left, Rachel Zoe went bananas at the Proenza Schouler show by mimicking the models who were sporting dark roots with champagne blonde hair.  At Narciso Rodriguez, socialite and Vogue contributor Lauren Santo Domingo reminded us how bad the recession must be if even socialites aren’t making extra trips to the salon.

Get the extra worn-in look by skipping a day or two of hair washing and instead use Bumble & Bumble Hair Powder ($17).  Whether you’re trying to get a messy style like Rachel Zoe, or you just don’t feel like washing your hair, this powder comes in every color to match your hair and hide greasy build up.

If you’re in between visits and aren’t trying to make a statement, try Oscar Blandi Root Touch-Up Pen ($23) instead of your normal hair colorist.  Avoid a pricey trip to the salon and do it yourself with this easy to use pen that comes in different shades.

Celebutantes from all over the world were sporting two-toned hair throughout the week.  British babe Alexa Chung debuted her line for Madewell alongside fellow root offender & pal Pixie Geldof; clearly friends that don’t dye together stick together.  Meanwhile over at Rachel Roy, Whitney Port let her trademark blonde locks fade, too. We’re not sure if everyone was too busy jetting to fashion shows to give a shout to their colorists, but celeb colorists beware: you may soon be losing your regular clientele.

Both Alexa Chung and Whitney Port have mastered the art of the effortlessly sexy bedhead look.  Try Herbal Essences Tousle Me Softly hairspray ($3.74) for loose waves without all the crunch of a regular hairspray.
